초록
An blockage-correction method using wall pressure distribution on the closed test section of a subsonic wind tunnel has been studied. The wall pressures on the test section and flows around a circular cylinder in the test section have been numerically investigated by solving compressible Navier-Stokes equations. The present method based on measured-boundary-condition method was validated by comparing a free-air condition and the results with Maskell's and Hackett and Cooper's methods based on the test results of a bluff body having edge separation. It was shown that the present method is in good agreement with the free-air condition, enabling better correction than the bluff body method.
Abstract
An blockage-correction method using wall pressure distribution on the closed test section of a subsonic wind tunnel has been studied. The wall pressures on the test section and flows around a circular cylinder in the test section have been numerically investigated by solving compressible Navier-Stokes equations. The present method based on measured-boundary-condition method was validated by comparing a free-air condition and the results with Maskell's and Hackett and Cooper's methods based on the test results of a bluff body having edge separation. It was shown that the present method is in good agreement with the free-air condition, enabling better correction than the bluff body method.
